After upgrading to 25.1, Network Prevent for Email servers stop processing email messages randomly. Restart of the DLP's detector server service works around the issue. After each restart email detection returns to full capacity until detection hangs again and requires another restart.

Environment

Cause

This is caused by random network drops that can cause email prevent to stop functioning.  Product Defect CRE-22907.

Resolution

This is addressed in 25.1 MP1.
